Title: Communication en semi-duplex dans un systeme duplex par repartition en frequence
Inventor: BHUSHAN NAGA
IPC: H04B7/26
Filed: 2007-05-18
Granted: 2013-07-30
Abstract: L'invention concerne des systèmes et des méthodologies qui assurent la communication en semi-duplex dans un système duplex par répartition de fréquence (FDD). Les communications dans un système FDD peuvent être divisées en entrelacements en semi-duplex, un terminal pouvant recevoir à un moment donné et émettre à un autre moment donné. Un réseau d'accès dans un système FDD peut alors utiliser la communication en semi-duplex pour communiquer avec un terminal d'accès qui ne peut pas émettre et recevoir simultanément en utilisant un entrelacement en semi-duplex. De plus, un réseau d'accès peut également utiliser la communication en semi-duplex pour communiquer avec un terminal d'accès pouvant émettre et recevoir simultanément.

Abstract: The invention relates to a cylinder piston arrangement for an especially volumetric fluid pump or a fluid motor, preferably comprising at least one axial expansion tubular membrane piston defining at least one inner pulsating working chamber. A particular field of application for such pumps or motors is the operation thereof with fluids loaded with extraneous materials, especially abrasive granulated materials. Especially high-speed machines with high working pressures of between a few hundred to a thousand bar are required, the energetic and also volumetric degree of efficiency thus becoming highly important factors. The aim of the invention is therefore to create pumps or fluid motors which are characterised by high degrees of efficiency and long service lives. To this end, at least one clearance driving body (TK1) is actively connected to the pulsating working chamber (AR).

Abstract: In a wireless communication system, a sender apparatus (1) sends a data block, for each of a plurality of stream data, with data block identification information, which does not conflict between stream data, annexed, and a reception apparatus (2) performs a re-sending synthesis process for a data block received already and a re-sending data block to which the same data block identification information is individually annexed based on the data block identification information annexed to the received data block. Consequently, also in a case wherein the number of transmission streams between the sender apparatus (1) and the reception apparatus (2) is varied (reduced) , the matching property of the data block which is a re-sending synthesis target can be maintained and communication can be continued normally.

Title: Outboard marine motor that allows a large steering angle
Inventor: INABA TAKESHI
IPC: B63H20/02
Filed: 2009-09-30
Granted: 2012-04-24
Abstract: In an outboard marine motor including an upper case (4) enclosing an engine (E) and a lower case (5) fitted with a propeller (12) and connected to a lower end of the upper case, the lower case is configured to be turned relative to the upper case around a vertical axial line which is coaxial with a vertical drive shaft (10) that transmit torque of the engine to the propeller. Thereby, the outboard marine motor can be steered simply by turning the lower case. Because the upper case having a relatively large lateral dimension as compared with the lower case is not required to be turned, a large steering angle can be achieved without the outboard marine motor interfering with watercraft having the outboard marine motor mounted thereon. In particular, the lower case is turned by an actuator including an electric motor and a worm gear mechanism (50) for transmitting an output torque of the electric motor to the lower case so that a high speed reduction ratio can be achieved by using a highly compact structure.

Abstract: A node device and a program of simple structures autonomously select an appropriate route without imposing a load on a network. In a node device 1 in a communication network, an FID management table 5 stores an FID for unique identification of a frame and the information about a destination node of the frame, and a weighting table 7 stores weighting information about another node as a destination for relay of the frame for each final destination node of the frame.  When a frame transmitted to a local node is received, and if the FID of the received frame is stored in the FID management table 5, the data about the destination node associated with the FID is updated. If the FID of the frame received from the frame reception device is not stored in the FID management table 5, the FID management table 5 corresponding to the destination node of the frame is referred to, and another node as a destination for relay of the frame is determined.
